Claims

[Scope of utility model registration request]

A tubular rotating pressurizing body to which the rotation of the drive roller is transmitted is made deformable using an elastic thin material, and while the rotating pressurizing body is held in an approximately cylindrical shape by guide rollers, the rotating pressurizing body is attached to the original and the thermal paper. The originals and the thermal paper are brought into close contact with each other by pressing them against a pressurized object formed by overlapping them, and the rotary pressurizing body is rolled along the surface of the document while pressing against the pressurized object,
In a thermal copying machine that sequentially irradiates infrared light from the infrared lamp onto a portion in close contact between the document and the thermal paper using an infrared lamp and a reflector supported in the rotating pressurized body to obtain a thermal copy, A belt is passed between the drive roller and the guide roller, and the belt is pressed against the cylindrical outer surface of the rotary pressurizing body, and the rotary pressurizing body is pressed against the object to be pressurized. A thermal copying machine in which a pressurized object is brought into surface contact with a pressurized object, and the movement of the belt is transmitted to the rotating pressurizing body so that the rotating pressurizing body is rolled along the surface of the document. Close contact structure with paper.
